FLAT-BED WEB PRESS- Specification of Letters Patent.

Patented June 25, 1907.

Application filed September 12,1906. Serial No. 334,270.

To all whmn it may concern;

Be it known that I, HENRY F. BEOHMAN, of Battle'Creek in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Flat-Bed \Veb Presses; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in flat bed type printing web presses, of the well known duplex type, and its objects are to produce a machine capable of printing and assembling as many as sixteen newspaper pages at each operation, and to so construct the press that its length will not be materially increased, although its width will be; and so that all the beds and cylinders will be low down and within easy reach of the operator from the floor; and to provide means for operating the sections of the press simultaneously or separately, and to provide novel means for assembling the several Webs at the folder.

The invention will be readily comprehended from the accompanying drawings, and I will now describe the same with reference thereto, and summarize the parts for which protection is desired in the claims.

In the drawings-Figure 1 is a top plan view of the complete machine, Fig. 2 is a detail diagrammatical view of the web collecting devices. Fig. 3 is a side elevation of the complete machine; and Fig. 4 is a vertical sectional elevation on line 4-4, Fig. 1.

The main frame of the machine is L- shaped in plan, and each leg of the L contains a perfecting mechanism A and B, respectively, which are arranged in substantially the same plane and constructed alike, each containing a pair of parallel type beds 1, 1 arranged one above the other, and a pair of impression cylinders 2 and coacting with beds 1, 1 The impression cylinders in mechanism A are journaled in cross heads 3 connected by pitman 3 to crank gear wheels 3 substantially as in the ordinary duplex press, said crank wheels being mounted upon a shaft 3. Similarly the cylinders in mechanism B are mounted in cross heads 5 connected by pitman 3- to gears 3 on a shaft 3 lying at right angles to F, being assembled 2 respectively shaft 3. The crank gears 3 mesh with pinions 3 on a shaft 3 and crank gears 3 mesh with pinions 3 on a shaft 3 The adjacent ends of shafts 3 3 at the angle of the machine are intergeared by bevel-gears 3 and 3 so that the shafts and the cylinders will be operated synchronously. The shafts 3 3 may be driven in any suitable manner, as by belts engaging pulleys 3 on the shaft 3 as indicated in Fig. 1 of the drawings, or by a belt to pulley 3 on shaft 3 as indicated in Fig. 3.

Each mechanism A and B is adapted to print a web which can be led in from rolls W and W located at the angle of the machine as indicated in the drawings. The course of the webs being similar in the respective per fecting nechanisnis of the press, the description of one will explain both. As illustrated in Fig. 4, the web W is led in from a roll to the feeding-inmechanism 4, under guide 4 up over looping roller 4 down under guide 4" to guide 4 then between cylinder 2 and bed 1, up over guide 4 out over guides 4 and 4 over guide 4 between cylinder 2 and bed 1 over guides 4 4 down to loopin roller 4 up to the delivery 4 down un der roller 4, and then the web is divided and one-half w is led over guide 4 to the folder F, situated at the angle of the machine; while the other half w is turned under deflector 4 and then over guides 4 and 4 to the folder there with the other half w of the web IN. The feed roller 4 and delivery rollers 4 are constructed and operated substantially as in the duplex press; and the looping rollers 4 and 4 are likewise constructed and operated substantially as in 'the duplex press by means of a frame 5 connected to a lever 5 operated by a cam 5 on shaft 5 The guides 4 and 4" travel with cylinder 2, and guides 4 4 travel with cylinder 2*. The other web W is led from the roll WV through the part B, which is constructed similar to part A, and after passing the delivery rolls, the web Vi is split, and both halves 10 and w are passed over an angle-bar 6, extending across the angle of the machine, as shown in Figs. 1 and 3, and then one-half w of the web passes over a guide 6 down over guide 6 to the folder F, where it is assembled with the halves w, w of the web WV, while the other half w of the web IO If Wiis deflected over angle bars 6, 6 then turned over and under guide 6 where it is brought parallel with the first web w and is then carried over guide 6 to the folder F, where it is assembled with the other portions of the web as shown in Figs. 2 and 4 of the drawings. If each section is printing a fullwidth web, a sixteen-page newspaper can be produced at each operation of the machine. one section is printing a full-width and the other a narrow width web, a ten, twelve or fourteen page newspaper can be produced according to the width of the narrow web.

The construction and operation of the machine will be obvious from the foregoing description and the economy of floor space, accessibility of parts, increased capacity, steadiness of running, and facility of threading the press will be obvious to any one skilled in the art.

If it is desired to produce newspapers of only eight pages or less, one set of perfecting mechanism can be thrown out of operation,- as by slipping the gears 3 3 out of mesh, so that but one section of the press need be operated.

Having described my invention what I claim as new and desire to secure by Letters Patent is 1. In a printing press, the combination of two perfecting printing mechanisms arranged at right angles to each other, and each comprising two stationary beds and coacting impression cylinders, means for reciprocating the cylinders over the beds, gearing between the cylinder driving mechanisms, a folding mechanism at the angle of the press, and means for directing the webs printed in both mechanisms to said folder.

2. In a printing press, the combination of an L-shaped main frame, a pair of parallel stationary type beds secured in each leg of the main frame, reciprocating cylinders coacting with said beds, web feeding, looping and delivery mechanisms adjacent each pair of beds, guides for directing the web between the beds and cylinders, a folder in the angle of the press, and angle bars and deflectors adjacent the folder whereby the webs can be assembled at the folder,

3. In a printing press, the combination of two flat-bed-web-perfecting printing mechanisms arranged at substantially right angles and in the same plane, folding mechanism at the angle of the press, and means for assembling the products of both mechanisms.

4. In a printing press, the combination of two perfecting printing mechanisms arranged at right angles to each other each comprising two stationary beds and 'coacting impression cylinders, means for reciprocating the pairs of cylinders at right angles to each other, gearing between the cylinder driving mechanisms, and folding mechanism.

5. In a printing press,- the combination of two flat-bed-web-perfecting-printing mechanisms arranged at substantially right angles and in the same plane, each comprising two stationary beds and two reciprocating impression cylinders, means for operating the mechanisms synchronously, and a folding mechanism at the angle of the press.

6-. In a printing press, the combination of an L-shaped frame, a pair of parallel type beds secured in each ell of the frame, a cylinder operating on each type bed, folding mechanism at the angle of the press, and web guides substantially as described whereby the Webs printed on both sets of type beds can be assembled at the folder.

In testimony that I claim the foregoingas my own, I affix my signature in presence of two witnesses.
